摘要:

由Jahn-Teller活性离子引发的本征晶格畸变可降低配位几何结构的对称性及其d轨道简并度, 从而稳定催化剂表面的反应中间体, 并有效调控电极材料在充放电过程中的电子与离子电导率, 进而显著影响材料的宏观性能. 本文系统阐述了Jahn-Teller畸变的起源与诱发机制, 概述了其主要表征方法, 并重点讨论了该效应在催化转化及能源存储等功能材料领域的应用, 旨在为深入理解Jahn-Teller畸变与材料宏观性能之间的构效关系提供参考.

关键词: Jahn-Teller畸变, 轨道简并, 对称性

Abstract:

The intrinsic lattice distortion induced by Jahn-Teller-active ions reduces the symmetry of the coordination geometry and the degeneracy of d-orbitals, thereby stabilizing reaction intermediates on the catalyst surface and effectively regulating the electronic and ionic conductivities of electrode materials during charge-discharge processes, which in turn significantly influence the macroscopic properties of the materials. This review systematically elucidates the origin and triggering mechanisms of the Jahn-Teller distortion, outlines its primary characterization methods, and highlights the applications of this effect in functional materials such as catalytic conversion and energy storage, aiming to provide a systematic reference for an in-depth understanding of the structure-property relationship between the Jahn-Teller distortion and macroscopic material performance.

Key words: Jahn-Teller distortion, Orbital degeneracy, Symmetry
